[Changes in left-ventricular function in chronic congestive heart failure treated with digoxin, furosemide and vasodilators].
48 patients (62.8 +/- 9.1 yrs) with III or IV NYHa class congestive heart failure after 2-week therapy with digoxin (D) and furosemide (F) underwent two-dimensional echocardiographic examination to assess left ventricular function. Then in 25 patients (group I) DF and nifedipine (N) were given within 2 weeks, D, F, N and captopril (C) within 4 weeks and again D, F, N within 2 weeks. In 23 patients (group II) isosorbide dinitrate (S) was administered instead of nifedipine. 2-DE examination had been performed at the end of the each study stage. Optimal daily drug dose were: D-0.34 +/- 0.07 mg, F-40.7 +/- 12.5 mg, S-44.3 +/- 10.4 mg and 75.8 +/- 26.4 mg. Nifedipine and isosorbide dinitrate administrated with digoxin and furosemide did not improve left ventricular function in comparison with a standard therapy (DF). The best positive changes were observed in both groups during treatment with captopril. Ejection fraction by Teichholz increased from 42.9 +/- 15.0% during DF stage to 45.2 +/- 11.5% (DFNK stage) in group I (p less than 0.001) and from 35.3 +/- 10.5% to 36.4 +/- 10.4% in group II respectively (p greater than 0.01). Left ventricular systolic and diastolic internal diameters significantly decreased (p less than 0.05) whereas stroke volume and cardiac indices nonsignificantly increased (p greater than 0.05). Captopril with digoxine, furosemide and nifedipine caused significant hemodynamic improvement. Effect of captopril with nifedipine was greater that of captopril with isosorbide dinitrate.
